Dropping clues has always been a bit of a weird archetype. One that, I believe, is like the opposite of doom archetypes for Mystics.
In almost every scenario, getting clues is a MUST to progress at least some part of the scenario. In some scenarios you'll even need EVERY clue on the board. This means dropping clues is like undoing your hard-earned progress. Reverse action economy if you will. In a way, it's the opposite of doom archetypes since those eat your future actions, while this one, in a way, eats your past actions. (Altho Doom can be taken care of before it fucks you up).
Then, comes Press Pass. Now returning clues to their location is no longer such a lost of progress when you can LITERALLY gain an action to get it back. Hell, using Deduction or Other investigation tools, you can actually get more than what you lost!
